Good news is that Ruby and Rails are there. Bad news is that they are in the last position! But don't despair, because we have this other list, extracted from http://tiobe.com. This one is updated till this month and if you want to go there to see for yourself, this is the link.

As you may see, Ruby jumped from the position 16 to the position 10! This is really good news.

On the other hand, languages like C#, Objective-C, Delphi/Object Pascal and COBOL are going down every new month. A good message for those who intend to spend time and money with them: Don't do it! Pick another language!
